[1] Their coinage in Chaganian was an imitation of the Sasanian coins of Khusrau I, with sometimes the addition of the name of local rulers.
According to H. A. R. Gibb, the expeditions against Chaghaniyan and other areas east of the Oxus river seemingly indicated “a methodical plan of conquest” of Soghdiana by Ziyad.
[13] In 705, the Arab general Qutayba ibn Muslim managed to make the Chaghan Khudah, whose name is mentioned as Tish, acknowledge Umayyad authority.
The real reason for Tish's submission, however, was to gain aid in defeating the local rulers of Akharun and Shuman in northern Tokharistan, who had been making incursions against him.
He was a loyal supporter of the Samanid ruler Nasr II (914-943), who in return, rewarded him by appointing him as the governor of Khorasan.
In 945, the Samanid ruler Nuh I dismissed Abu 'Ali from the governorship of Khurasan after hearing complaints of the latter's harsh rule,[16][11] and sought to replace him with a Turk, the Simjurid Ibrahim ibn Simjur.
He was joined by several prominent Iranian figures such as Abu Mansur Muhammad, whom he appointed as the commander of Khurasan.
Abu 'Ali also convinced a Samanid, Nuh's uncle Ibrahim ibn Ahmad, to come from Iraq and installed him as ruler in Bukhara when he took the city in 947.
Fortunately for Abu 'Ali, he managed to secure the support of other Samanid vassals, such as the rulers of Khuttal, and the Kumiji mountain people, and in the end made peace with Nuh, who allowed him to keep Chaghaniyan in return for sending his son Abu'l Muzaffar Abdallah as hostage to Bukhara.
A certain Muhtajid prince, Abu'l Muzaffar ibn Muhammad, probably the grandson of 'Abu Ali, was then appointed as the new ruler of Chaghaniyan.
[11] By the end of the 10th-century, the Muhtajid dynasty became a vassal of the Ghaznavids, who had replaced the Samanids as the dominant power in Transoxiana and Khurasan.
During the reign of the Alp Arslan (r. 1063–1072), his brother Ilyas ibn Chaghri Beg was appointed as the governor of Chaghaniyan.
